Figure 4. Comparison of future and historic areal mean rainfall accumulation for all 41 HPEs analyzed (a-b, Sect. 3.2), and the regional maximal 10-min rain rates (i.e., along all the pixels in the region and throughout timesteps) (c-d, Sect. 3.4). Scatter plots (a, c) compare the historic (horizontal axis) and future (vertical axis) values. Violin plots (b, d) show the distribution of historic (pale colors) and future (bold colors) quantities for the different sub-regions (Fig. 1b). Each dot along the violin represents a value of one HPE, white dots are median values, and gray boxes are the inter quartile range. The change between medians of historic and future events is marked with dashed lines. Statistically significant differences between the paired-event populations for each region (presented also as scatter plots in Fig. S3 and S7) are marked here with ** (see also Table 1).
Table 1: Changes in rainfall properties between future and historic simulations. Bolded numbers are statistically significant (i.e. on both paired t- and paired Wilcoxon signed-rank tests, Sect. 2.4). Italics are significant on the paired t-test only. The upper value represents the entire region and below are values for each sub-region (land, sea, med=Mediterranean, and des=desert, Fig. 1b).
